Chronic gastritis includes superficial and atrophic, chronic superficial gastritis can generally be cured after 6~8 weeks of drug treatment after removing the cause of the disease, but atrophic chronic gastritis generally cannot be cured. Chronic non-atrophic gastritis combined with Helicobacter pylori infection using eradication treatment quadruple therapy generally 10~14 days, not combined with Helicobacter pylori infection, need to be treated for 1~2 weeks. Gastric mucosa with mild superficial gastritis, if there is no Hp infection and no erosion, asymptomatic, generally do not need special treatment; however, if the patient has uncomfortable symptoms or gastroscopy found active inflammation, the first thing to do is to remove the cause of the disease, such as smoking, medication, or bacterial infections, and then by drug treatment for about 6-8 weeks generally can be cured. Chronic atrophic gastritis may be accompanied by intestinal epithelial hyperplasia or heterogeneous hyperplasia, which may pose a risk of cancerous transformation and requires patients to undergo regular gastroscopy to monitor the pathological changes in the gastric mucosa. Chronic non-atrophic gastritis should be treated with Helicobacter pylori eradication if it is found to be positive for Helicobacter pylori. Currently, bismuth quadruple therapy is mostly used in clinical practice, i.e., 1 proton pump inhibitor + 2 antibiotics and 1 bismuth agent such as omeprazole, clarithromycin, metronidazole, and bismuth potassium citrate. It usually takes 10 to 14 days; 1 to 2 weeks of treatment for uncomplicated H. pylori infection. The diagnosis of chronic gastritis requires gastroscopy and histologic examination, and it cannot be diagnosed on its own by clinical manifestations alone. If the patient is diagnosed with chronic gastritis, it is recommended that the patient actively seek medical treatment and standardize the treatment under the guidance of the doctor.
